Poor weather obscured Kanaga during most of the past week. Observers in Adak reported seeing steam and possibly minor ash rising a few thousand feet above the volcano earlier in the week. No pilot reports of continuing eruptive activity at Kanaga were logged by FAA and NWS.

VENIAMINOF

Residents of Perryville were able to see Veniaminof Volcano on Thursday. A slight steam plume over the volcano was noted.

The Alaska Volcano Observatory continues to seismically monitor Spurr, Augustine, Redoubt and Iliamna volcanoes. We maintain a computerized alarm system that is capable of notifying AVO seismologists during non business hours should unusual seismic activity occur.
